Multiquip EE54878 Cummins QSB7 Hydraulic Pump Adaptor - OEM Replacement Part

The hydraulic pump adaptor interfaces the Cummins QSB7 engine with the generator's hydraulic actuation system, specifically enabling operation of hydraulically-controlled components like the roof ventilation door that opens during engine startup. This precision-machined adaptor ensures proper pressure transfer to hydraulic cylinders that control the intake air ventilation system on the SG1400C4F Studio Generator.

This component is critical for generators equipped with hydraulic roof ventilation systems. On startup of the diesel engine, hydraulic pressure fills the cylinder through this adaptor connection, opening the roof door to allow intake air to pass across the engine's radiator for cooling. The adaptor must maintain proper seal integrity to prevent pressure loss that would compromise ventilation door operation.

Designed for the Cummins QSB7-G9 Tier 4 engine platform featuring 6 cylinders, 409 cu. in. displacement, and turbocharged with charge air cooling. This engine produces 282 HP at 1800 RPM in the SG1400C4F application.
